REGKLINGHAUSEN, GERMANY METHOD 0F `REATING COKE OVENS Application iled January 30, 1928, Serial No. 250,664, and in Germany January 31, 1927.

The purpose of the invention is to provide and vmaintain uniform temperature conditions throughout coke oven chambers regardless of the height to which the latter may be built. To this end the invention consists in the provision of a heating systemin which a small amount of highly heated air is mixed with the gases before the latter pass into the lower ends of a plurality of vertically disposed distributing pipes located within the heating flues of the coke oven. The distributing pipes are provided with discharge openings located at various heights and combustion supporting air is supplied to the iues in sufficient quantity to effect combustion at said openings. The air initially supplied to the gases serves to prevent decomposition of the gases prior to combustion at the openings through which the gases pass from the distributing pipes to the heating lues.

A coke oven embodying the principles of the invention is illustrated in the accompanyin drawing in which:

igure l is a vertical longitudinal section taken on the line A`B of Figure 2, and,

Figure 2 is a vertical cross-sectional view taken on the line C-D of Figure l.

The heating-gas, required for heating, is supplied to the individual oven during the respective heating-period by the heating-gas conduit a, or al and in heating the left hand half passes for instance by means of the connecting-pipes b or b1 (Fig. l) into the gas distributing-channels c and 01, respectively, disposed below each heating-wall half. It is there distributed through the different nozzles d, d1, of which one each has been provided for every heating-flue. The required air for combustion is taken from the regenerators g and 7c provided below the coking-chamber f. The air coming from the regenerator g through the channels z', strikes in the mixing-chambers h first the gas-current coming from the nozzles (l, whereby mixing and partial combustion are effected. The gases mixed with a partial volume of air, pass into the distributing-pipe Z or Z1, vertically arranged in every heating-flue and provided vwith lateral openings m. The gases escape through the openings m, m1 at various heightsV into the open space of the heatingflues, where a complete combustion up to the top of the vheating-fines takes place gradually by means of air entering from the regenera- Y v JIgor 7c through the ducts n into every heating- The waste heat gases produced during Y tion, but sufficient tov prevent decompositiony under the inliuence of the surrounding heat, separately supplying vto the flues secondary air suflicient with the amount in the mixture aforesaid to support combustion, and then conducting the mixture of gas and air fir-st mentioned tol 'various .distributing points spaced lengthwise in the lues, whereby combustion is effected at the distributing points. In testimony whereof I have a-iixed my signature.
